Embodiment 1

[0023] Embodiment one, with reference to Figure 1 to Figure 3 As shown, the embodiment of the present invention provides a device for adjusting the angle of a light bar, including at least two light bars 40 , a longitudinal beam 70 for connecting the light bars 40 , and a crossbeam 60 for fixing the longitudinal beams 70 , The back of the light bar 40 is provided with a connecting end 50, the end of the connecting end 50 is movably connected with the longitudinal beam 70 through the joint shaft 51, an adjusting rod 20 is arranged parallel to the longitudinal beam 70, and the middle part of the connecting end 50 is arranged There is a positioning shaft 52 connected to the adjustment rod 20. According to the above technical solution, the light bar angle adjustment device provided in this embodiment, when specifically adjusting the irradiation angle of the light bar 40, after moving the adjustment rod 20 up and down, The connecting end 50 is driven to rotate around the joint sha...

Embodiment 2

[0028] Embodiment two, refer to figure 1 and Figure 4 to Figure 6 As shown, the main difference between this embodiment and Embodiment 1 is that the surface of the longitudinal beam 70 is provided with a fixed mark 30, and the connecting end 50 is movably connected with the fixed mark 30 through the joint shaft 51, and the connection The positioning shaft 52 in the middle of the end 50 is connected with the adjustment rod 20, and the fixed mark rod 30 is provided with a scale 31 at either end, and the end corresponding to the adjustment rod 20 and the scale 31 is provided with a pointer 22, and the pointer 22 points to The scale 31, the light bar 40 moves the connecting end 50 with the joint axis 51 as the axis to reach the required inclination angle under the action of the adjustment rod 20 moving up and down, in order to limit the The amount of relative position change between the fixed benchmark 30 and the adjusting rod 20, the fixed benchmark 30 is provided with a fixed ...

Embodiment 3

[0030] Embodiment 3. The embodiment of the present invention provides an LED display screen, including a signal transmission circuit, a power circuit, a control circuit, and the light bar angle adjustment device described in the above embodiment. The light bar angle adjustment device is assembled into an LED display screen, and the LED display screen assembled according to the above technical scheme is aimed at the special situation of different angles required for different heights of buildings. A certain inclination angle gradually rises or falls, which is convenient for the audience to appreciate.

Abstract

The invention provides a lamp bar angle adjustment device. The lamp bar angle adjustment device comprises at least two lamp bars, longitudinal beams which can be connected with the lamp bars, and transverse beams which can be fixed with the longitudinal beams, wherein connecting ends are arranged at the backs of the lamp bars; the tail ends of the connecting ends are movably connected with the longitudinal beams by joint shafts; adjustment rods are arranged at the tail ends of the connecting ends parallel to the longitudinal beams; and locating shafts are arranged in the middles of the connecting ends, and connected with the adjustment rods. With the adoption of the technical scheme, when the lamp bar angle adjustment device particularly adjusts illumination angles of the lamp bars, after the adjustment rods are moved up and down, the connecting ends are driven to make rotary motion by taking the joint shafts as axes, and limited and located by the locating shafts, so that angles of the lamp bars are adjusted; the downward or upward inclination degree number of the lamp bars is the same; operation is convenient; the angles are unified; and the technical problems in the prior art are solved.

Description

technical field [0001] The invention belongs to the field of LED display screens, in particular to an adjustment mechanism capable of adjusting the angle of a display screen light bar. Background technique [0002] In the prior art, the outdoor LED display adopts a unit box design, that is, the LED light bar is installed in a frame, and then the entire frame is transported outdoors for construction. Such products are generally used for building lighting, publicity Advertising, including indoor or outdoor, as a tool for distributing information, LED display can publish various information such as text, pattern, video display, etc. Usually, LED display is a dot matrix module or display pixel composed of light-emitting diodes Unit, when the LED display screen is used outdoors, it is very important to meet the visual requirements of the human eye for the screen body to emit light. The emitted light cannot be completely seen by human eyes, which will affect the display effect of...
